SCREEN FOR-DOORS AND WINDOWS.

Specification of Letters Patent.

Patented Aug. 8, 1 905.

Original application filed September 12, 1903, Serial No. 172,994. Divided and this application filed March 31, 1904:. Serial No. 200,941.

have invented a new and useful Screen for Doors and Windows, of which the following is a specification.

The invention relates to improvements in screens for doors and windows and is a division of my application filed September 12, 1903, Serial No. 172,994.

The object of the present invention is to improve the construction of screens for doors and windows, more especially the means for permitting the flies to escape from the interior or inner face of a screen.

A further object of the invention is to provide a simple and comparatively inexpensive fly-screen of this character adapted to cause flies crawling upward to pass from the interior to the exterior and to prevent such insects from passing from the exterior to the interior.

With these and other objects in view the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in the form, proportion, size, and minor details of construction within the scope of the claim may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is an elevation of a portion of a screen constructed in accordance with this invention. Fig. 2 is a vertical sectional view of the same. Fig. 3 is a horizontal sectional view of a portion of the screen. Fig. 4 is a detail perspective view of a portion of the screen. Fig. 5 is a detail view of a por tion of the corrugated fly-escape strip. Fig. 6 is a detail view illustrating the manner of applying the invention to an old screen.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

1 designates a screen-frame having a corrugated fiy-escape strip 2 interposed between its top bar or piece 3 and the upper edge of the screen material A. The screen may be either a door or window screen, and the screen material is wire-gauze of the ordinary construction. The fly-escape strip 2 is constructed of sheet metal or other suitable material, and it is provided at intervals with transversely-disposed corrugations 5, consisting of approximately semicylindrical bends which extend outward from the intermediate straight or flat portions 6 and which are provided at intervals with perforations for the reception of fastening devices 7. The flyescape strip is located wholly beneath the screen material, and the projecting bends fit against the inner face of the same. The straight flat intermediate portions are fitted against the window or door screen frame, and every other one of the projecting portions or corrugations 5 is perforated, and the fastening devices 7 secure the upper edge of the screen material and the corrugated fly-escape strip to the screen-frame. The intermediate portions 6 may also be provided with perforations for additional fastening devices when desired. The projecting portions 5 of the flyescape strip space the upper, edge or portion of the screen material from the top of the screen-frame and form fly-escape openings or passages to permit the flies crawling up the screen to pass from the interior or inner face of the same to the exterior thereof. The upper edge of the screen material 4 extends upward beyond the fly-escape strip to provide a projecting flange or portion 9, and the screen material is of sufficient length for this purpose when the invention is applied to new screens; but when the invention is applied to old screens a strip or piece 10 of molding will be applied to the lower edge of the top bar of the screenframe, as illustrated in Fig. 6, to increase the distance between the lower edge of the top of the screen and the upper edge of the screen material.

A strip 11 of wire-gauze or other suitable material is interposed between the fly-escape strip and the top of the screen-frame and is extended above the former to provide a projecting flange, which is arranged parallel with the flange 9 to form a transverse passage the entire Width of the screen. This strip 11 is secured to the screen-frame by the fastening devices for securing the fly-escape strip to the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a fly-screen for doors, windows, &c., the

combination with a screen-frame, and a covering of screen material, of a transverse fly-escape strip interposed between the top of the frame and the screen material and located wholly beneath the upper edge of the latter, and provided with projecting bends which fit against the inner face of the screen material and support the latter, said bends being of a greater size than the interstitial openings of the screen material and serving to space the screen material from the top of the frame and form fly-escape openings, the screen material being extended beyond the fly-escape strip to provide a projecting flange, a separate strip of screen material arranged between the fly-' OLAUS B.
